LG explains:
The botched rollout in an ignominious development for the first Android Wear watch to feature a SIM card for voice calls and data service directly on the watch. LG hasn’t yet told us what the hardware problem is, but during testing I’ve found problems with WiFi and LTE performance. In short: Google Now voice commands don’t work reliably unless the Urbane 2nd Edition LTE is tethered to my phone.
You can read all about my problems with the watch here.
I’ll update this story if and when LG sheds more light on the issue. 9to5Google reports AT&T is offering refunds and exchanges for the Urbane 2nd Edition LTE. So there’s that.
